Either use this in the "from" page: <INPUT TYPE=HIDDEN NAME=previous VALUE='<?=htmlentities($PHP_SELF)?>'> Or use $_SERVER['HTTP_REFERER'] in the "to" page. Or is it $_ENV['HTTP_REFERER']? I can never remember what comes from which. Use <?php phpinfo();?> to be sure. Note that some browsers may choose to give you very strange things for HTTP_REFERER, but PHP_SELF is pretty much going to be what you set it. On the other hand, it's trivial for a hacker to alter your INPUT TYPE=HIDDEN tag and send whatever they like. In either case, you can't trust the data you are getting, since any bozo could make it be anything they want. -- Like Music? http://l-i-e.com/artists.htm
